Abstract

The physico-chemical studies were conducted on the citrus fruits of sweet orange cv. Mosambi Local-1, 2, 3, 4 and 5 and Sweet Mandarin cv. Chinese Orange, Kinnow, Nagpur Mandarin, Local Mandarin-1 and Local Mandarin- 2. The Sweet Orange cultivar was highest size in Mosambi Local-3 with maximum fruit volume 204 ml and flesh weight 139.66 g followed by Mosambi Local-4. The juice recovery percent was maximum in Mosambi Local-3 28.63 and the highest specific gravity was found in Mosambi Local-1 (0.99) followed by Mosambi Local-2 (0.94). The different cultivars of Sweet Orange were recorded varies from the total soluble solid 7.60 to 12.66 per
cent, reducing sugar 4.13 to 7.08 per cent, total sugar 5.90 to 10.12 per cent, tritrable acidity 0.52 to 0.83 per cent, ascorbic acid 46 to 74.80 mg/100g and pH 3.92 to 4.98. The juice percent was determined in Kinnow 53.20 g after that Nagpur santra 51.30 g. The chemical attributes of Sweet Mandarin were found as total soluble solid varied from 8.96 to 12.20 per cent, reducing sugar 3.22 to 6.60 per cent, total sugar 5.73 to 10.04 per cent, titrable acidity 0.84 to 2.24 per cent, ascorbic acid 25.96 to 36.13mg/100 g and pH 3.84 to 4.60. However, the Sweet Orange cultivars Mosambi Local-3 and Mosambi Local-4 and Sweet Mandarin cv. Local Mandarin-1 were suitable for export, making of non alcoholic beverages, easy for bottling and frozen products grown under Lucknow conditions.
